NAME
       gfs2_quota - Manipulate GFS2 disk quotas


SYNOPSIS
       gfs2_quota <list|sync|get|limit|warn|check|init|reset> [OPTION]...


DESCRIPTION
       gfs2_quota is used to examine and change quota values in a GFS2
       filesystem.  This command has a number of different actions.

       GFS2 introduced a new linked list format for the quotas in the quota
       file.  This list format allows for faster list, check and init
       operations. Older GFS2 quota files may be migrated to this newer format
       using the gfs2_quota reset command.


ACTIONS
       list   List the contents of the quota file.  Only IDs that have a non-
              zero hard limit, warn limit, or value are printed.

       sync   Sync any local quota changes to the quota file.

       get    Get the current data for the ID specified by the -u or -g
              argument.

       limit  Set the current hard limit for the ID specified by the -u or -g
              argument to the value specified by the -l argument on the
              specified filesystem.  The filesystem won't let the user or
              group use more than this much space.  A value of zero here means
              that no limit is enforced.

       warn   Set the current warn limit for the ID specified by the -u or -g
              argument to the value specified by the -l argument on the
              specified filesystem.  The filesystem will start complaining to
              the user or group when more than this much space is used.  A
              value of zero here means that the user won't ever be warned.

       check  Scan a filesystem and make sure that what's out there on the
              disk matches what's in the quota file.  This is only accurate if
              the filesystem is idle when this is running.  If there is a
              mismatch, it is printed to stdout.  Note: GFS2 quotas are
              transactional and a quota check is not needed every time there
              is a system crash.

       init   Scan a filesystem and initialize the quota file with the values
              obtained from the scan.  The filesystem should be idle when this
              is run.  You should only need to do this if you upgrade a pre-
              quota GFS2 filesystem (pre-GFS2 5.1).

       reset  The reset operation will truncate the quota file and all quota
              information (values, limits, warnings) will be lost.  All quota
              limits and warnings will have to be reassigned after this
              operation.


OPTIONS
       -b The units for disk space are filesystem blocks.

       -f Directory
              Specifies which filesystem to perform the action on.

       -g GID Specifies the group ID for get, limit, or warn.  It can be
              either the group name from the group file, or the GID number.

       -h     Print  out  a  help  message  describing  available options,
              then exit.

       -k     The units for disk space are kilobytes.

       -l Size
              Specifies the new value for the limit or warn actions.  The
              value is assumed to be in the units specified by the -m, -k, -s,
              -b arguments.  The default is megabytes.

       -m     The units for disk space are megabytes.  This is the default.

       -n     Don't try to resolve UIDs and GIDs into user and group names.

       -s     The units for disk space are sectors (512-byte blocks).

       -u UID Specifies the user ID for get, limit, or warn.  It can be either
              the username from the password file, or the UID number.

       -V     Print program version information, then exit.


EXAMPLE
       To set the hard limit for user "nobody" to 1048576 kilobytes on
       filesystem /gfs20

       gfs2_quota limit -l 1048576 -k -u nobody -f /gfs20
